MEANS FOR SECURING CHANNELS OR GUIDEWAYS OF FIRE-RESISTING BLINDS R DOORS.

SPECIFICATION forming part of Letters Patent No. 681,326, dated August 27, 1901.

Application filed June 22, 1901. Serial No. 65,625. (No model.)

To (.tZZ whom it may concern:

Be it known that I, WILLIAM R. KINNEAR,

A a citizen of the United States, residing at 00- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Means for Securing the Channels or Guideways of Fire Resisting Blinds or Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Metallic fire resisting blinds and doors such, for example, as are shown in my Letters Patent of the United States No. 57 2,014, dated November 26, 1896'are engaged by and run in channels or runways at the sides of the window or door opening.

The object of my present invention is to .provide improved means for quickly, economically, and firmly securing such channels or runways in place.

The invention is embodied in a spur adapted to be passed through a portion of the channel and into the brick or framework at the side of the window or door opening, said spur having a seat to receive the end of an extensible bar between two of such spurs, whereby the channels or runways are secured in place.

In the accompanying drawings, illustrating an embodiment of my invention, Figure 1 is a horizontal sectional view through the channel-securing devices, but broken out near the middle. Fig. 2 is an oblique perspective View of the spur.

In the views, 1 designates the spur, and 2 a cupped or sooketed head formed therewith. In the bottom of the socket or cup 2 is a square or non-circular socket 8 for the purpose hereinafter explained.

The channel is shown to be formed of two pieces of angle-bar 4 and 4*, a web of one belocated at any suitable number of points, but preferably in pairs at opposite sides of the window or door opening, such pairs being in the same horizontal line. A tube or pipe 6 a trifle shorter than the clear distance between the heads of the spurs and containing in one end a screw 7-, with a squared end '7, and a nut S is then placed between the heads of the spurs, the end of the tube fitting in the cup 2 on one spur and the squared end of the screw 7 fitting in the square socket of the other. In practice the squared end 7 of the screw can be first placed in one socket 3, when upon turning the nut 8 in the proper direction the pipe 6 will be fed toward and tightly into the socket 2 of the opposite spur. The two spurs are thus locked from movement and the channels held firmly in place.

When the described devices are used for fas tening channels or guideways for doors, they will of course be placed so high and so low as not to impede the passage-way through the door.

Viewed together the pipe 6, screw 7, and nut 8 constitute an extensible bar. Other forms of extensible bar can be substituted for that shown and described. The headed spurs, it will be observed, are shown to be alike and interchangeable, each being adapted to receive either the end of the pipe or the end of the screw. This saves expense and facilitates the application of the devices. Obviously the shape of the spur and its head can be modified.

What I claim, and desire to secure by Letters Patent, is-

1. Means for securing blind or door channels or ways in place comprising headed spurs adapted to engage opposite channels or ways,

combined with an extensible bar between the.

heads of such spurs, substantially as described.

2. Means for securing blind or door chan-- nels or ways in place, comprising headed spurs adapted to engage opposite channels or ways, combined with an extensible bar between the heads of such spurs consisting of a pipe or tube adapted to fit the head of one spur and a screw to engage the head of the opposite spur, substantially as described.

3. Means for securing blind or door channels or ways in place, comprising headed spurs adapted to engage opposite channels orways, combined with an extensible bar between the heads of such spurs consisting of a pipe or adapted to engage such channels or ways and the brick or other framework of the window or door opening, and means extending between 15 the channels or ways to lock said spurs from movement, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM R. KINNEAR.
